Solving the Realtek HD Audio error : Error 0xE0000227

There is really only 1 way to install the Realtek HD Audio drivers properly. No matter what all other forums say. Service Pack 3 is the main culprit as the drivers see that its above SP2 and dont install. I personally face this situation and was really distressed because it looked like either i will have to reinstall Windows Xp or have my new supercool and super monster computer without sound. Imagine having a monster PC with a motherboard with HD Audio and your driver doesnt install.

Both scenarios were something which i would never have approved of. Anyway so i Googled. I got 10s of solutions but most didnt work. Only 1 worked and i will put it here hoping that Google dear will catch it and people who face this problem installing the Realtek HD Audio 0xE000027.

  1. First Step is to make sure all instances Realtek Audio and its associative softwares are uninstalled from add remove programs and device manager. This includes Intel High Definition audio.
  2. On your PC change the CSDVersion registry key to Windows XP SP2:
    HKLM\SYSTEM\CurrentControlSet\Control\Windows\CSDVersion value=200

This problem arises as the patch thinks that SP3 includes a better version of the patch itself and hence doesn’t install itself.

3. Download the latest drivers from the Intel website, navigate to the KB888111 patch.

4. But before installing the patch, goto your device manager and disable the UAA. Now uninstall the UAA.

5. Install your patch now.

6. Install the Realtek drivers now and things should work.

7. Change the SP version to 300 again.

If it didnt work, try once again. I can enjoy 7.1 channel high definition sound from my Intel Original motherboard now. Realtek HD Audio now works fine. Hopefully Error 0xE000027 is fixed now.

  1. Go to Device Manager/Device Drivers

    Disable microsoft UAA bus driver …

    Try to Uninstall UAA bus driver…i cannot, reboot then uninstall. If u get install

    new hardware wizard after reboot cancel it.

    Unistalll ANY sound device u had before (sound card or onboard chip)

    Reboot… cancel new hardware wizard….

    Install realtek driver and it will work…after Realtek sound is working,

    reboot…accept new harware wizard, it will then install UAA bus driver again,

    and everything will work just fine!!!

  2. Thank you. Thank you. Thank you. I just went through 24 hours of Windows hell. Only to have this happy little turd surprise waiting for me upon the OS reinstall. Worked like a charm. Keep on posting!

  3. Dear all friends, i am also facing the same problem, but i can’t find the UAA in device manager pls advise how to find that in device manager.

  4. Wow! Now that was cool. I had Windows xp sp2 installed on my computer. But, upon installing drivers I too came across the same problem of sound. So, i googled the problem and found this tech blog. I did as said. Note here that the above solution works for Win xp sp2. I didn’t have that much trouble. For those of you who don’t know where to find hklm i.e. that above link, here’s the solution. Just go to the run command in the start menu and type regedit. HKLM stands for ‘HKEY_LOCAL_MACHINE’. Then you will be able to find where to change the csd version by going according to the link. Sometimes for ControlSet it will be ControlSet001. Choose that. Then go as per the instructions given above. Choose to download the KB888111 patch from because it’s safe. In device manager UAA will be found under System devices. If it is not present, continue with the installation else disable and uninstall it. Proceed as above. Upon installing the KB888111 patch itself upon restarting the sounds will come.
    Next install the realtek drivers. You’re then up in no time.

    Wishing you happy computing!

  5. The solution given is excellent. It solved the hectic problem of my audio driver. Thanks for the solution. I disabled, uninstalled Microsoft UAA from device manager. Then realtek was installed. Then rebboted ths system. When it prompted for the messgae of ‘some updates will be done if not restarted’ rebboted my system. I could hear sound. Excellent approach!!!!!

  6. Thanks, this solved the Audio problem on my PC, otherwise 0xE0000227 was very troubling for me.

  7. Oh mt goodness i’ve worked on this all day and followed your directions and it worked! Thank you so much!

  8. Dude, you’re a life saver! Helping friends updating their computer, I lost sound as described by you. Thanks for putting this on the web.

    Note: it’s 1-2011 now – the (latest) drivers still give this error. LAME!

  9. I spent hours and was just going to try a reinstall when I found this and it worked.


  10. Hi From South Africa (XP SP3)
    After going through the sequence (CSDVersion 300 to 200 etc), I have lost the ability to execute .exe files. I found (but cannot find again) a comment that stated that after the install sequence if drivers dont load, then there is a hotfix.. Would you know what this hotfix is and where I could find it? Thanks.
